7.3.5.3 Humidity High

When HH_ENABLE is set and the humidity is over the threshold value program in the Humidity Threshold HIGH register, the HH_STATUS bit is set to 1. The HH_STATUS bit and the DRDY/INT pin behave based on the INT_POL and INT_MODE bits.

The INT_MODE bit sets the threshold to either comparator mode or a level sensitive alarm.

When INT_MODE is set to 1, the HH_STATUS bit is based on the current humidity conversion. The polarity of the DRDY/INT pin is set by INT_POL.

When INT_MODE is set to 0, the HH_STATUS bit remains set to 1 until it is read. The polarity of the DRDY/INT pin is set by INT_POL.
